I have DSD hen. It's as realistic as they come...I may be the odd ball in the group but I'd be scared to death to put out a gobbler decoy that was as realistic as the DSD's. I'm afraid some over anxious hunter is going to get me in a spot where I find myself in line of fire with the object of his desires!
What I've done, and it's worked out phenomenally well, is use one of those stupid looking Funky Chickens. I don't think anybody is going to mistake that for the real thing...Gobblers seem to be really aggressive toward it so it does what it's meant to do. I can just stick in in the same carry bag as my DSD hen...Hey. it looks stupid but it works...Oh, and it's about 1/4 the price of a DSD ( Of course that wouldn't matter if it didn't work).
